Minor question:
fast moving objets in video are generally problematic, because in some parts of video the display needs then more bits/sec and frames/sec to maintain video quality.

Does Mencoder or/and konttori's Converter produce a variable (VBR) or constant (CBR) videobitrate?

konttori 2005-12-07 21:27

Mencoder can do it for mpeg1, but apparently not for mpeg4. However, with two-pass encoding, the encouder should be able to make a nice version that should smooth out the problems in the fast moving parts. Mencoder supports this and it shouldn't be too hard to add to Media Converter.

Although, apparently there may also be problems in nokia 770 itself in decoding fast paced action.

You can download full mencoder from:

So, I have successfully encoded a video using Media Convert on Mac OS X.

Thank you, sir.

New version available for Windows!
 
Media Converter 0.3 has been released.
New in this version is the ablity to encode usinng two-pass coding, which gives much better quality results. It is well worth the extended encoding time. However, I felt it was still nice to leave it as an option. What do you think? Option or as default and not changable?

Oh, and some people have been asking about the file formats, according to mencoder site, it supports the following formats:
* MPEG-1 (VCD) and MPEG-2 (SVCD/DVD/DVB) video
* MPEG-4
* MJPEG, AVID, VCR2 and ASV2
* DivX
* 3ivx
* Windows Media Video 7/8 (WMV1/2)
* Windows Media Video 9 (WMV3) (using x86 DLL)
* RealVideo 1.0, 2.0 (G2)
* RealVideo 3.0 (RP8), 4.0 (RP9) (using Real libraries)
* Sorenson v1/v3 (SVQ1/SVQ3), Cinepak, RPZA and other QuickTime codecs
* DV video
* Intel Indeo3 (3.1, 3.2)
* Intel Indeo 4.1 and 5.0 (using x86 DLL or XAnim codecs)
* VIVO 1.0, 2.0, I263 and other H.263(+) variants (using x86 DLL)
* FLI/FLC
* HuffYUV
* various old simple RLE-like formats

Most of these should work on media converter, but if not, please let me know!

You can download it here:

I'll try to release OSX version of 0.3 later today.

Very nice work. Can't wait to get home and test it.

I think option is better. I at least like the fact that you can sometimes encode videos with faster speed, even though you loose some quality.

Maerra 2005-12-08 21:00

I have some home "videos" made from still pictures (slideshow) where changing the picture to next one is the only movement. I experimented with Mencoder and decreased framerate down to 8 fps: no visual difference against 15 fps. So, it should be useful to have adjustable framerate too in konttoris' Converter.

BTW, does the two-pass encoding produce variable videobitrate (VBR)?

Works great. Thanks!
 
I'm running Windows 2K Pro and it works like a charm for my MPEG4 movies. Man , I love this device. :)

Is the Mac version ready? :D

Small Issue
 
Just downloaded and tried to run the latest version- it does its job, but the file it generates doesn't have the .nokia770 suffix, nor does it include the whole filename, at least with 2 pass encoding checked. Any ideas?

konttori 2005-12-11 21:04

well, osx version might work, but i haven't tested it yet.
windows installer had a bug and i've updated the setup.exe just a few mins ago.

AzM: what windows version do you have?
